Conversion Instructions Section 5-19
Any or all of the digits in S may be converted in sequence from the designated
first digit. The first digit, the number of digits to be converted, and the half of D
to receive the first 7-segment display code (rightmost or leftmost 8 bits) are
designated in Di. If multiple digits are designated, they will be placed in order
starting from the designated half of D, each requiring two digits. If more digits
are designated than remain in S (counting from the designated first digit), fur-
ther digits will be used starting back at the beginning of S.
Digit Designator The digits of Di are set as shown below.
Some example Di values and the 4-bit binary to 7-segment display conver-
sions that they produce are shown below.
